Sarafloxacin is a synthetic, third-generation fluoroquinolone antibiotic developed primarily for veterinary and microbiological research use, exhibiting potent broad-spectrum bactericidal activity against Gram-negative and selected Gram-positive pathogens. It is a key reference standard in antimicrobial residue analysis, veterinary pharmaceutical development, and in vitro susceptibility testing for food-animal and aquaculture pathogens.
Niraparib is a highly selective, potent oral PARP inhibitor used primarily in oncology to treat various forms of cancer, particularly ovarian and prostate cancers with BRCA mutations. It is designed as a targeted therapy to exploit DNA repair deficiencies in tumor cells, offering high efficacy with manageable side effects for patients requiring maintenance treatment after chemotherapy or as a monotherapy in recurrent settings. The product is available in high purity suitable for both pharmaceutical research and clinical development purposes.
Calcitonin, porcine is a highly purified, 32-amino acid polypeptide hormone naturally synthesized by the thyroid C-cells of pigs, supplied as a sterile lyophilized white powder for advanced endocrinological and osteological research. Structurally characterized by a disulfide bridge between Cys1 and Cys7 and a C-terminal proline amide, this peptide shares high sequence homology with human calcitonin, making it a vital tool for scientists studying calcium homeostasis, bone metabolism, and G-protein-coupled receptor (GPCR) signaling. Its well-defined conformation and specific biological activity make it an essential reference standard for pharmaceutical R&D, biochemical laboratories, and academic institutions focused on antiresorptive drug discovery, hypercalcemia mechanisms, and the comparative physiology of calcitonin receptors across mammalian species.
Antho-RFamide is a high-purity, synthetic pentapeptide neuropeptide (pGlu-Gly-Arg-Phe-NH2) originally isolated from marine cnidarians such as the sea anemone Anthopleura elegantissimaand the sea pansy Renilla köllikeri, supplied as a lyophilized white powder for advanced neurobiological and evolutionary research. As a canonical member of the RFamide family of neuropeptides, it features a signature C-terminal Arg-Phe-NH2 (RFamide) motif and an N-terminal pyroglutamate residue, making it a fundamental tool for scientists studying primitive nervous systems, neuromuscular junctions, and G-protein-coupled receptor (GPCR) signaling. Its well-defined sequence and potent bioactivity make it an essential reference standard for academic laboratories, marine biology institutes, and pharmaceutical R&D teams focused on neurophysiology, comparative neuroscience, and the exploration of novel GPCR ligands derived from marine organisms.
CTX IV (6-12) is a synthetic peptide fragment corresponding to the C-terminal telopeptide region of type I collagen, specifically cleaved by the enzyme cathepsin K during bone resorption. This high-purity peptide serves as a critical reference standard for researchers studying bone turnover, osteoporosis, and other metabolic bone diseases, offering reliable calibration for ELISA and mass spectrometry assays.
β-Amyloid (1-34) is a synthetic peptide fragment representing the N-terminal region of the full-length β-amyloid protein, which is critically involved in the pathogenesis of Alzheimer’s disease. This peptide is widely used in neuroscience research to study amyloid aggregation, neurotoxicity, and early-stage plaque formation, offering researchers a valuable tool to investigate disease mechanisms and potential therapeutic targets in both academic and pharmaceutical settings.
